This property has a documented history as a public works and maintenance facility going back to 1931. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
This property served as a Snohomish County road maintenance shop from 1931 until the mid-1960s, accumulating petroleum contamination consistent with decades of vehicle and equipment servicing. Cleanup efforts to date have included demolition of a site building and excavation of over 2,670 cubic yards of TPH-impacted soil in 2000, followed by removal of an additional 410 tons of contaminated soil in 2005, with both batches treated by thermal desorption. The site remains in the Standard Cleanup program with further remediation anticipated. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
Why Historical Insurance Policies May Be Accessible
Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.
The cleanup costs this property still faces — additional investigation, remedial design, and any further soil or groundwater work — could plausibly be funded by the historical carriers who insured Snohomish County's operations at this facility during its 1931-to-mid-1960s active period, when occurrence-based CGL policies were standard. The petroleum contamination documented here traces directly to those decades of county road-maintenance activity, and the remediation expenditures already incurred — large-scale excavation, thermal desorption, building demolition — further establish the magnitude of the loss those same policies may be obligated to cover.
